The Debug column has Debug as title and Debug as value sometimes. Though no meaning can be deduced from this. Even reading the source code I was having a hard time to reall understand that column until I understand that souce files have been compiled with debug flag.
This column should be more descriptive. The column title should say "Debug Information" the value should be, as in other columns either "Yes" or "No"/"-".
I could provide a patch if requested. This is just a few lines of source.
